<p>
    查找提供相似接口的现有子系统或组件。可能已使用可重用资产规范（RAS）封装了一些资产以供内部复用。如果使用 Rational XDE 创建，则此类资产可以在 XDE 中浏览和装入。请参阅 <img alt="帮助手册图标"     src="./../../../core.base_rup/resources/helpbook.gif" /> <i>Getting Started with RAS Assets</i> 
    <!--//ReferenceHelpTopic(topicTitle,"ras","ras_o_getstart_rasset");     -->.
</p>
<h3>
    <a id="Reverse Engineer Components and Databases" name="Reverse Engineer Components and Databases">反向设计组件和数据库</a>
</h3>
<p>
    对于不包含 XDE 模型的资产，反向设计模型以便更好地理解设计可能会很有帮助。如果该资产被证实为可使用，则 XDE 模型将成为您的总体设计模型的组成部分。 <!-- begin - wsw -->请参阅 <img alt="帮助手册图标"     src="./../../../core.base_rup/resources/helpbook.gif" /> <i>Reverse Engineering</i> 
    <!--//ReferenceHelpTopic(topicTitle,"vs","intro/vs_c_getstart_rte_upd_mdl");     -->. <!-- end - vsnet -->
</p>
<p>
    对于您公司控制的资产，对候选接口做出较小的更改是有可能的，这将提高该接口与期望接口的一致性。对于您的公司未能控制的资产，您可以创建适配器或网桥设计元素，将您期望的接口映射到复用的资产提供的接口上。 请参阅<a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/toolmentors/identifying_design_elements_F8D68BA1.html" guid="{E6727D13-BE7B-4025-AD39-ECD6FA074D73}">工具向导：确定设计元素</a>，获取关于创建和修改接口和类的指南。
